Abstract (en)

A method for continuously developing an exposed silver halide photographic material containing a hydrazine derivative by an automatic processor, wherein the development is carried out by using a developer being substantially free from a dihydroxybenzene compound and containing an ascorbic acid and/or a derivative thereof as a developing agent, an aminophenol derivative as an auxiliary developing agent which exhibits a superadditive property and at least 0.5 mol/liter of a carbonate as a buffer, and wherein the developer is replenished with a developing replenisher having a pH at least 0.2 higher than that of the starting developing solution. In a preferred embodiment, the developing replenisher contains a silver stain inhibitor represented by the following general formula (1): <CHEM> The symbols in the above general formula (1) are defined in the specification.
